The article presents a new scheme and the principle of operation of the gear train with compound wheels including shock absorbers-bushes made of rubber. Analytical method was used to obtain formulas for calculating the angular shifts (strains) of bushing-bushings taking into account their thickness, shear modulus and transmission parameters.

The paper presents the dynamic model of the machine assembly with a recommended mechanism for moving material and the definition of the law of rails motion under various system parameters. The author has suggested the solution implemented by the system of differential equations numerically on the PC and the system describing the motion of the machine set. Recommended values ​​of the parameters of elastic links of material transfer mechanism have been obtained. The researcher has developed the methods of kinematic and dynamic analysis of the material transfer mechanism with elastic elements of the sewing machine and has approved the parameters and development of the design.

The article provides the kinematics chart of mechanism of material movement of sewing machine and determination of law of lath motion at the different parameters of the system and its equalization. It also determins concrete values of linear speed of point Е of lever – laths at moving of material in sewing machines. A mechanism is worked out with the storage of energy as a conical spring, that operates at the horizontal moving of lath and a mechanism is executed as the reserved kinematics chain.

В данной статье рассматривается проблема развития ОАО «РЖД» Дирекцией по ремонту пути на периоды с 2015 по 2030 гг. Автором анализируется путевая машина Duomatic 09–32 CSM, являющаяся на данный момент самой эффективной по сравнению с предыдущими аналогами отечественного и импортного производства. В работе изучается ее модернизация с целью улучшения эксплуатационных характеристик.
